Hello Ryan. My two cents. Its all about stability in flight. I've found that even 2 fletchings work just as well as 4. Thats just my opinion but there is allot of historical president to be found online. Maybe its just about what you have at hand.

i like the idea of 4 fletch. reason being is either way you nock it its fine. that being said id keep them long and very low.,kind of like plains fletchings but 4 instead of 3.i always have a mess of 2 feather { full feather} fletches simular to Catawba and Eskimo style fletches. mainly because its real simple flys great and you can even use very small feathers that most folks would turn their noses up at. even dove wing feathers i used worked great this way. so as im walkin in the woods i come across a few feathers here a few there then left and righty them up when i get home toss one on one side of a shaft the other match on the other side simple as it gets and costs 0 dollars and 0 cents no need for a jig, and a bunch of other stuff like that.i like keeping it simple.and cost effective.i found that even on two feather fletched arrows you can trim them down in higth quite a ways without any wobble.also since they are smaller feathers they bend down quite easily when rubbing against the bow on release. they dont tend to get the crap beat out of them like softer 3 feather conventional fletches do.{ the reason i think id like a 4 fletch low and long}.

Fletching serves to slow the back end of the arrow down and to make it spin. Both Stabilizes the arrow.

As said, two feathers work fine, because the slow it down and make it spin. The number of feather to their height and length (surface area) will determine how much drag you impart. You can have anywhere from Turkish flight arrows with 3 tiny feathers to flu flu arrows with 6 full height feathers. They all work, but do different things.

I would agree that the real advantage lays in being able to nock a shaft without worrying about cock feather orientation on the bow.  If this is an issue for you then I can see some utility in the four fletch.
But I think the popular received opinion about difference in effect on accuracy between three-fletch cock feather-out and cock feather-in is not so great as some folks suppose.
It might be interesting one day to run a blind test, but it's not something I worry about.


My objection to four fletch would be first, that I think it inelegant and second, that it represents a certain amount of extra work and material which I do not regard as necessary.


Those who rely on received wisdom would probably also tell me that I will lose distance by shooting three-fletch 5"x 3/4" parabolic cut RH helicals, not realising that the distance lost to drag is largely compensated for by the improvement in recovery from paradox.
In this context loss of cast is insignificant.


In practice what's the important issue? And how stiff are the vanes? Is it really so hard to nock with a consistent cock feather orientation and how great is the effect of cock feather-in nocking at a given distance?
Can you actually prove the difference by a blind test or is it really only a preference?


(Preferences are important if they serve a real function, rather than being an affectation).

after carefull thought on 4 fletch. in my oppinion, and understand im just using basic reasoning here, that if i were to make a 4 fletch it would be because of the ability to nock either way. also i rethought my statment earlier as well. if i were to make a 4 fletch, because of additional drag of a additional feather, id make them low but short enough to not go past the bow at brace.so most of my bows at brace are 4 1/2 inches . this being said id make them no more than 4 and a half inches long.the objective here is to fletch a arrow a hunting or practice arrow so it gets as fast as flight possible while still being stabilized in flight with a shorter shoot shaft arrow. the kind i shoot.but ill be honest here. i can make half a doz. 2 feather fletch arrows in the time it takes to make 2-3 properly made 3 feather fletch arrows. that being said, i just preffer the 2 fletch for obviouse reasons here.i dont go through the pulling off 2/3rds of one side of the fletch as is commonly reffered to as the Cherokee 2 fletch. actualy it was used by many tribes in the east.just 2 full feathers or cut down feathers if they are larger feathers works great for me. ive shot 3 fletch, 3 different styles of 2 fletch and i just like two full feather fletch arrows. fly great. take less time to make, nocks from either side, allows me to use smaller feathers that normaly couldnt be used. i even like this set up on my atlatl darts as well.

In my experience the greatest cause of drag with any fletching is the amount of flutter ( compare a high fletch flu-flu to the same shaft with a regular fletching), so a higher fletch of inappropriate shape is more likely to produce an obvious decrease in cast than would the increase in number from two to three or four fletches.

Some primitive methods of feather attachment also create more flutter which (especially if loosely attached) will reduce cast.

As a general rule of thumb, the more it flutters, the larger the amount of drag.

i agree, but i got the two fletch full feather fletch down to a science on my arrows for my bows .lol not alot of drag, just enough. i have my son stand in close proximity to a target i let go a arrow. hes close , but not so close to possibly be hit mind you. if he can hear it i know the fletches are too high. causing too much drag/flutter, but if its quite and flys well. its perfect. thats how i know how much to trim them down. i shoot them until i get good flight" and "its quite. i see some huge 2 feather fletches on youtube. , i mean i know they make noise. i know because mine arent very big at all. and work great. i can imagine a squirrel rabbit, what have you jumping that arrow. they know its coming from a good ways away. now mind you i dont i mind them knowing theres a arrow, but its because , well, its stuck in them.lol
